How to spot a fake BEGi FMU

A new development has occurred. There are eBay sellers, that are BEGI distributors, selling FMUs that are over one year old. The serial number stamped on the bottom of the FMU indicates that the FMUs are approximately 15 months old, but are being sold as a brand new unit. Use caution, as these item's warranties have already expired.  

Some of the Fuel Pressure Regulators or Fuel Management Units today are a direct copy of BEGi's unit. We have been fixing the knock offs for years. A word of caution - they do not work! Here is how to spot a fake of our 2020 FMU series. This does not apply to the MR regulator series or the older cast regulator series.

We recently ran across a fake unit. To the casual observer, it would appear to be a BEGI unit. But there were very minor differences. I would suggest that all EBay sellers post better photos, unless they want to be listed as selling a fake/ falsely advertised unit. If verification is need, do not hesitate to send us photos for verification.

1. 99% Chance it is Fake - A unit that does not have 'BEGI" on the top. We have shipped some units without the BEGi on it several years ago. However, most have it etched on there now. It will also have the serial # etched on the bottom of it.

2. Fake - The signal line fitting is at a 180 degree angle to the needle valve. Please note, the brand new FMU design is at a 180 degree angle, however, the FMU is not as tall. More info

3. Fake - Any unit sold by Cartech, EIP Tuning, or ProTurbo Kits. Cartech and BEGi are not the same company. They have not been associated for ten years. Cartech has copied the BEGi unit, and gone so far as to have BEGi stamped on the top to pass it off as a BEGi unit. Preston Marshall even refers to himself as Corky Bell on the phone.

4. Fake - The needle valve is pointed in an upward direction. Or perpendicular to the FMU conical surface. Some units have been repaired by BEGi and point the needle valve upwards, however that is a very rare occurrence.

5. All BEGi units will be stamped with a 2 to 4 digit serial number on the bottom.

6. All BEGi units will be stamped with an 'IN'.  Some Fake units are also stamped with an IN.

7. We do have other means of identifying a fake unit. While Cartech copied it, they did miss a few details.

We do monitor the listings on e-bay, and do report all items listed incorrectly. We strongly recommend that photos of the serial # be taken.  If someone has listed an item incorrectly, we will inform them of the error and ask for correction. The e-bay item # is listed below along with description of the FMU. If this was a FMU / FPR made while BEGi and Cartech were the same company, it will be listed as a BEGi item.  This list is updated daily.

EBay Item # Status of Item: Date Added: 
201757237183 This is a probably an older BEGI FMU. The SN would need to be verified. The signal hosebarb is in a non-standard location, 12-26-16

This is an older BEGI FMU that is missing the needle valve and one way valve. 

They are available for purchase seperately if needed.

To clarify some statements made by Cartech:

"A quick note on other regulators: CarTech has been in business since 1975. We have never sold any of our regulators under any other name, period. All of our regulators are now and always have been designed and produced by Cartech. Even some of our former affiliates have gotten in on the act using our model numbers. Rest assured that when you buy a regulator from Cartech, you are getting our authentic piece and all service and repair parts that you may ever need, guaranteed. We will also be happy to service or repair any other brand of regulator that has seen fit to use our design."

First of all, Cartech was founded by Corky Bell in 1975, not Preston Marshall the current owner of Cartech. That is, unless Preston was a very capable toddler in diapers.

Second, a true Cartech FMU, design, assembly, components, part numbers, etc, were kept by Corky Bell when Cartech was sold to Preston Marshall and Mike Montgomery in 2000. Cartech was never sold the rights to the FMU/ Adjustable fuel pressure regulator. To imply otherwise is untruthful. The authentic Adjustable/Rising Rate FMU's remain in the hands of Corky Bell / Bell Engineering.

Lastly, any FMU made by Cartech is a knock off. It is 100% fake and chances are you will be sending it to us to make it work. Cartech has no concept of how the FMU works, so they were not able to copy it and make it work correctly.  Yes, the copied FMUs will have BEGi CNC'd on the top of it. However, due to some minor differences we are able to discern which part was made by BEGI and which part was not.
